SUNSPOT MONITORING – AUGUST 28, 2018

Here are today’s solar images taken from Al Sadeem Observatory, August 28, 2018.

The sky was mostly clear (with some high cirrus cloud passes) with moderate to strong air turbulence making the seeing and transparency average to poor at the time these images were taken.

Both visible sunspot groups AR2719 and AR2720 have decayed further in sunspot structure over the past 24 hours as they approach the western limb. No significant flaring activity associated with the two active regions (ARs) were recorded.  The latest sunspot number (based on visual count and Wolf number calculation) is 20.  Few fairly huge eruptive prominences at the eastern limb areas, and the huge stable filament at the Sun’s northern hemisphere were distinctively captured in H-alpha imagery.

Space weather agencies* forecast solar activity to remain at very low levels with chances of weak X-ray fluxes or flares ranging up to B-class intensity. The extent of the frequency and intensity of the Sun’s activity will highly depend on the magnetic flux fluctuations happening in the visible ARs in the coming days. Close monitoring is being conducted by numerous space weather agencies for any significant development.
